SPECIFICATION forning part of Letters Patent No. 435,530, dated September' 2, 1890.

Application filed April 7, 1890- Serial No. 346,979. (No model.)

To all whom tm/ay concern:

Be it' known that I, JAMEs TALLEY, a citi- Zen of the United States, residing at Denver,

in the county of Arapahoe and State of Colo-v rado, have invented certain new and useful Improvements inOre-Ooncentrators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which ro it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

I5 My invention relates to improvements in ore-concentrators of ithe class designed to separate the precious metals from the rock and gangue of pulverized, comminuted, or finely-crushed ores; and the object of my inzo vention is to produce a machine which shall not only separate the mineral from the gan gue, but which at the same time shall divide the concentrates into any desired number of grades corresponding with the different degrees of fineness to which the comminuted mineral is reduced. This I accomplish by the use of a series of tables arranged in steps one above the other and at a suitable inclination to the horizontal, the first or most elevated 3o table of the series having for' its object the usual functions of a concentrating-tablenamely, the separation of the material therein into tailings and concentrates, the latter being the.heavier and traveling gradually up the inclined plane of the table and over its edge to the table next below, while the tailings, being the lighter, work down the inclined plane of the table and over its lower edge to a chute, from which they may be car 4o ried to the lowest table of the series and there subjected to further treatment, if desired, or they may be discharged directly to the dump, as may be desired. All the taljles of the series after the first or most elevated, therefore,

have only concentrates to deal with, and their only function is the grading of the concentrates, the lighter or finer particles passing down the incline over the rear edge of the tables and into la suitable receptacle, while 5o the coarser and heavier particles pass up the inclined plane of the tables surface and over the headto the table next below, where said material is treated as before, and so on, a separate table being made for each grade of concentrates desired.

To this end my invention consists of the features, arrangements, and combinations hereinafter described and claimed.

In the drawings is illustrated an embodiment of my invention, in which- Figure l is an elevation of one side of the complete machine. Fig. 2 is a similar view of the opposite side of the same. Fig. 3 is a front end view of the machine. Fig. 4 is a rear end view of theA same. Fig. 5 is a top or plan view of the mixer. Fig. G is a section taken longitudinally through the-center of the mixer. Fig. 7 is a detail View showing part of one of the lower arms of the mixer. Fig. 8 is a front View of one of the concentrating-tables. Fig. 9 is a side view or elevation of the same. Fig. 10 is a detail View showing the manner of pivoting the lower extremity of the upright supports of the table. Figs. l1, 12, 13, and 14 are detail views of a 75 cam, showing also the connecting-rod or pitman, by means of which mechanism a reciprocating movement is imparted to each table of the series. The dierent gures show four positions of the pitman relatively to the parts of the cam. Fig. 15 is a front view in perspective of the distributer. Fig. 16 is adetail view of the shaft, pulley, and eccentric for giving the longitudinal movement to the distributer. Fig. 17 is an elevation of the screens, illustrating the mechanism by means of which the oscillating movement is imparted thereto. Fig. 18 is a top View illustrating the foraminous character of the screens and their different degrees of mesh in the order of their arrangement, the top screen being broken away to show the one beneath, which in turn is broken away to show the bottom one. Fig. 19 is an elevation, partially in section, illustrating the mechanism for imparting the longitudinal movement to the distributer.

In the Views let the reference-numerals 1 1, ttc., designate four upright bars or standards forming the frame-work for the head or forward portion of the mechanism. These bars are connected at the top by the cross-bars 2 2, dac. The lower extremities of the outer IOO bars 1 at the head of the machine rest upon the ground, the length of these bars being sufficient to raise the machine as far fromt-he ground as necessary or desirable.

3 3 are side beams on each side of thel frame, being suitably connected at the head of the machine with bars 1, and the opposite extremities to the short upright bars 4, forming the rear legs for the machines support, bars 3 being also centrally supported by additional legs 5. These legs 4 and 5 are shown broken awayin the drawings, yet they must be understood to rest upon the ground and form part of the support forthe mechanism. From leg 4 the extension side bars 6 continue for a short distance to the tail of the machine. To the rear extremity of the bars 6 are connected the short upright bars 7, from the top of which the bars 8 extend toward the head of the machine and in a direction parallel with bars 6. From the inner extremity of bars 8 are erected the vertical or upright bars 9. vFrom bars 3 oneach side and toward the-head ofthe machine extend the upright bars `10 to about half the height ofthe beams l at the head of the machine. The upper extremities of the bars 10 are connected with the two beams 1, farther toward the rear of the machine,`by means of the short horizontal bars 11. Bars 9 and 10are connected on each side of the machine by the horizontal side bars 12. To the under side of the lowest side bars 12 are secured `the short vertical bars 13, which make a right-angular turn toward the head of the machine and merge into the horizontal bars 14, which are parallel with bars 12 and are connected at their forward extremity to the upright bars 10, as shown.

The entire frame-work of the machine as constructed and as herein shown consists, preferably, of tubular bars, resembling the ordinary gas-pipe, of a size proportionate to the weight of the mechanism and the load to be supported thereon. By the employment of this construction of frame I obtain the required strength for the purpose of the machine with a minimum weight of material.

It' may be well to observe that whileIhave described a suitable frame-work for my machinethearran gement and connection otl tubular bars is only typical of any other 'similar arrangement or connection that might be employed.

Between the cross-bars 2 at the top of the machine is suitably pivoted and suspended the rocking hopper 15, provided with two wedge-shaped compartments 16.

17 is the rocker-arm rigidly secured to the hopper at one extremity, its opposite or lower extremity being pivotally secured to the connectingrod 18, the opposite extremity of which rod is secured to the wrist 19 of the eccentric 20, the eccentric being made fast to the outer extremity ot' the shaft 21, suitably journaled at 22 22 to the extension-bars 24, made fastat their inner extremities to twoV of the upright bars 1 ot' the main frame. i

Shaft 21 is alsoprovided with a pulle`ywheel 23. This shaft is themotor-shaft of the machine, and to it power is applied by means of a crank or in any other suitable manner for giving motion to all parts of the machine by virtue of the connection and arrangement of the mechanism, as hereinafter described.

Beneath the hopper 15 there is arranged a series of screens 25, 26, and 27, each screen having the flanges or rims 120, the sides of which iian ges are provided with small pulleys or rollers 28, which engage or rest upon tracks 29 as the screen moves back and -forth under the iniiuence of suitable propelling mechanism. As shownfin the drawings, each of these screens isconnected by a rod J with an upright bar K, which is pivoted at its .lower ex- 25, 26, and 27, as shown at O. An oscillating l movement is imparted to bar .K andthe screen with which it is connectedby an eccentric P, secured to shaft 21, the eccentric being connected with the bar K by a rod Q, having one extremity secured to the strap of the eccentrics and the opposite extremities hinged or 1pivoted to the bar K. AThese screens are ar- ;ranged according to the Iineness of their mesh, lthe coarser being the highest, and'so on.

Each screen is provided at one end with'a discharge 30, into which passes the coarse material which the "spring rejects, `this coarse `material passing thence from the dischargeispouts to a chute '31, which carriesit fromthe machine to the dump. The finer material which passes through the screensis finally discharged into `the stationary hopper 32, formed -with two wedge-shaped dischargespouts 33 33, from which the material passes through chute 135 to the mixer 34,which consists of circular compartments 35 35, Vcommunicating with each other by means of an aperture 36, formed in the lower portion of the adjoining. partition walls.- Compart- `ments 35 are inclosed in a single jacket 37, leaving a space 38 between the jacketand the walls of the mixer. Space 38 forms a passage or channel through which heat is passed around'the compartments of the mixer for the purpose of warming the material therein to any desired degree and maintaining the pulp at the proper temperature.` Hot air or steam may be used for this purpose. `The heating medium, as steam, passes into the chamber 38 through one extremity of a pipe 39, which is connected with any suitable source of steam-supply, andout at the other extremity after having passed around'the mixer. A pipe-may be 'coiled around the mixer within space 38, forming a continua. tion of pipes 39 39, one of said pipes 39 forming the inlet and the other the outlet forthe steam or hot air. The pipe within the'space may be coiled any desired number oftimes around themixer. The two compartments 35 tremity to short `horizontal bar L, as shown at' M. Each rod J is suitably pivoted at one ex-l tremity to uprightbar. K, as shown at N, and at its opposite extremityto one of .the screensV IIO ' ing therewith.

of the mixer are exactly alikein construction. Each has a conicalv bottom 40, with the apex in the center, the Vsides of the cone sloping gradually to the walls of the receptacle, as shown. In the center of each receptacle is a vertical shaft 4l, having its lower extremity pointed and resting upon the apex of the bottom. The lower portion 42 of each shaft 41 is square at 42 and provided withacollar 43, y

of corresponding shape, sufficiently loose thereon to have a free vertical movement back and forth upon part 42 of the shaft.

To each collar 43 4are rigidly secured the agitators 44, consisting of two radial arms made fast. to the collar at opposite points. To the outer extremity of each of these arms are adjnstably secured the extensions 45, which telescope within arms 44, being provided with pins or lugs 46, which move back and forth within slots 47 of the agitators. This construction allows the agitators to adjust themselves to the conditions of the material within the mixer by moving up and down upon the shaft or changing the length of their arms.

To the upper portion of each shaft 4l and near the top of receptacles 35 is another sleeve 48, rigidly secured upon the shaft and turn- To each sleeve 48 is rigidly secnred'a pairof arms 49, the arms beinglocated on opposite sides of the sleeve, as shown.

To the top of each shaft 41, which extends considerably above the receptacles 35, is rigidly secured a pulley 50, one of said shafts being provid ed with an extra pulley 51, which is connected with a pulley 52 upon motorkshaft 21 by means of a belt 53. Bythis means motion is communicated to one shaft 41 and from this latter shaft to the other similar shaft of the same name by means of a belt 54, which connects pulleys 50. l

The material after reaching the mixer is supplied with sufficient water for its proper treatment, or the water may be added to or mingled with the material when it is first introduced to the hopper 15, if deemed desirable. expedient in the treatment of ores, it is not deemed essential to show any mechanism for this purpose. After thorough treatment within the mixer in the manner described the material passes thence through a suitable pipe or spout 55 t-o the distributer 56, which consists of a trough supported across the machine in front of the mixer and slightly below the same, so that the material passes from the one to the other by its own gravity. The distributer is supported by and pivoted to the suspension-rods 57, which are pivotally secured at their upper extremities to thehorizontal bars 58, which are rigidly secured to two of the standards 1 and fxtend forward therefrom to a point directly above the distributer, so that rods 57 when at rest. hang normally in a vertical position.- The distributer obtains a lateral or transverse movement from an eccentric 59, secured to abar 60, suitably journaled at 61 and 62 to the standards The use of water being an ordinary beginning with the highest.

1 and 9, respectively. Rigidly secured to bar 60 near its upper extremity is the small pulley 63, having a groove in it's'periphery and connected with a smaller pulley 64 on motorshaft 21 by means of a suitable belt 65. Motion is communicated from shaft 21to shaft 60 by means of the belt 65 and the pulleys which it connects.

66 is a connecting-rod, one extremity of which is suitably secured to the strap of the eccentric 59, the other extremity of said rod .being 'hinged or pivoted to the adjacent suspension-bar 57. This mechanism gives the lateral movement to the distributer when power is applied to the shaft 2l, or a longitudinal movement or a movement at right angles to the lateral movementj ust described may be imparted to the distributer. This is accomplished by means of connecting-rod A, suitably hinged at one extremity to the distributer, the opposite extremity being secured to the strap of an eccentric B, rigidly secured to a shaft C, journaled in suitable boxes D, lnade fast to two of the bars 1 of the framework.

E is a pulley mounted upon shaft C and connected by means of a belt H with another' pulley F, mounted upon shaft 103. Power'is communicated to shaft 103 in the manner hereinafter described, and thence tothe distributer by virtue of the mechanism just described.

Pipes 157 carry off the surplus water from the distributer.

The function of the distributer is suggested in its name, and consists `in distributing the material received from the mixer evenly upon the first table of the series heretofore mentioned.

67 is an inclined plate or chute conducting the material from the distributer to the first table. The passage of this material from the distributer is regulated by means of a slide 68, operated by a lever 69, a ratchet 70, and suitable connecting-bars 71, 72, and 73.

' Hence at the will of the operator the material passes from the distributer to the first or most elevated table of the series, which tables I will designate by the numerals 74, 75, 76, 77, and 78, in the order of their elevation, These tables are all of similar or identical contour and supported and operated in the same manner. In Figs. S and 9 are shown, on an enlarged scale, a front view and a side view, respectively, of one of these tables.

The upper portion of each table or the table proper consists of a plate composed of metal or other suitable material, having its surface divided longitudinally or divided on the line of the machines length by the parallel strips 17 S. The forward extremity of each table is provided with a spirit-level 79, for use in controlling and adjusting this por- ICC IIO

tion of the table, which should at all times y be maintained in a horizontal position.

legs 80, suitably hinged or pivoted to the uuder side of the machine at one extremity and at the opposite extremity seated in sockets 81, formed in the lop of suitable supports 82, made fast to the transverse side bars 83, seated upon and made fast to the side bars of the frame, which'engage the recesses 84, formed in the lower edges ot' bars 83.

Each table is provided with two springs 85 and 86. Spring 85 occupies, normally, a verticalposition, and is made fast, at one extremity to the under side of the table proper and at the opposite extremity to suitable stationary bars 87 below. Spring 86 occupies a sort of diagonal position, being secured at one end to the under side of the table near its forward extremity and at the opposite end to the stationary bars S3 below and near the rear extremity of the table. The springs tend to keep the table normallyin the upright position.

S8 88, &c., are water-pipes extending across the machine above the tables, which they supply with water sufficient for the treatment of -the material thereon. The water passes from the main pipes through the smaller pipes 89, which are supplied with faucets 90 for regulating the supply. Pipes 88 are supported upon suitable standards 191.

Each table is provided with bumpers R, rigidly secured to the stationary transverse bar 83. A metal plate S, secured to the under side of the movable top portions of the table, engages the bumper R during the movement of the table, ashereinafter described. Each of these tables is given a reciprocating move ment through the medium of a pitman 91, suitably pivoted at one extremity to each side of the table, as shown at 92, the opposite extremity vof each pitman being connected with a cain 93 of peculiar construction. Each of these cams consists of a disk 94, an arm 95, and a pin or lug 96. These disks are rigidly secured to the opposite extremities of shafts97, which extend transversely acrossy the front of the machine, being suitably journaled to and supported by two of the vertical bars 1 of the framework. To each disk is pivoted, at a point 98 outside of its center,

the short arm 95, to which arm-is pivotally' securedat 99 the forward extremity of a pitman 91, said pitman point of attachment being far enough from the pivotal point of the arm to give the desired length of stroke to the pitman.

The shafts 97 are arranged on'a vertical line, one above the other, and correspond `in number with the tables uto be operated. Each 0f these shafts is provided with a pulley 100, rigidly secured thereto. Each pulley 100 is connected with a pulley 101,' rigidly secured to a shaft l03,suitably journaledto the outer vertical bars 1, forming part of the' frame-work of the machine heretofore described. Shaft 102 hasa pulley 101 for each pulley 100 on shafts 97. Hence each pulley 100 on a shaft 97 is connected with a corresponding pulley 101 on shaft 103 by means of a suitable belt .i bars 1 of the frame-work. Shaft 107 is pro? vided with a pulley 109, rigidly secured thereto. Pulley 109 is` connected with pulley 23 on the motor-shaft 21 by means of abelt 110.

fromY shaft 21 to shafts 97, whose movement gives the tables the desired reciprocating movement by virtue of the pitman-rods extending from the tablesto the cams 93. y The.

`It will be seen that motion is communicated action of these cams will be better understood by reference to Figs. 11, 12, 1,3, and 14. ,y

In describing the operation of thecam` I will suppose that the parts are in the relative positions shown in Fig.,11, the tables having just sprung forward, under the inuence of the spring-rods and 86, to their` forward limit of motion, engaging the bumpers R and giving the tables that sudden jar incident to such actions. When the disk 94 has made about one-half of another revolution, ythe pin 96 has traveled from the position shown in Fig. 11 to Athat shown in Fig. 12, where it eugages the arm` 95, which engagement continues until the arm again springs from the pin to the position shown in Fig;11,the parts occupying in the meantime a variety of positions, two of which only are illustrated-.- namely, those shown in Figs. 13 and 14. In Fig. 13 the parts are shown just beforethe pitman is drawn backward, to its extreme limit, while in Fig. 14 the parts are Vshown ,in their relative positions when the pitman has reached its limit of backward movement, being the position directly opposite that shown in Fig. l1, theV arm and the `pitman in both cases lying parallel or in a direct line with each other. The least movementfrom the position shown in Fig. 14 in the direction indicated by the arrows throws the pitman and arm out of line with veach other or' destroys their parallelism, and the arm and the pitman immediately spring again away from the `pin 96 to the position shown in Fig. 11, being actuated by the spring-rods 85 and 86, connected with the tables. This action of the tables aiects the material thereon in the manner heretofore described. The first or more elevated table 74 separates the `material thereon into concentrates and tailings, the former passing over the more elevated front portion of the table to the table 7 5 next below, while the tailings pass to the transversely-inclined spout 111 to the longitudinally-inclined spout 112 or to the dump, "as may be required. It' it is deemed necessary to re-treat the tailings,

IOO

IIO

they are carried by chtite 112 to a suitable distributer 113, and thence through the spout 114 to the last table 78, where the material is subjected to the same treatment that it originally received on the rst table. Distributer 113 is operated in a manner similar to the distributer 56, whose operation has been heretofore described. Distributer 13 is supported by rods 116, pivoted at their upper extremities to cross-bar 117, connecting the vertical bars 9 9. The lower extremities of rods 116 are hinged to the distributer 113.

Secured to the inclined side of bar GO, heretofore described, is an eccentric 177, to the strap of which is secured one extremity of the connecting-rod 11S, the opposite extremity of this rod being suitably hinged to the distributer. Hence as soon as bar 60 is set in motion a lateral movement is given this distribnter, the same as a similar movement to distributer 56. IVhen it is not desired to re-treat the tailings from the iirst table, they are of course carried to the dump, and in this case table 7 S is elevated sufficiently to form one of the series of tables and collect the mineral passing from the higher extremity of table 77 next above.

The grading of the concentrates upon the remaining tables 75, 76, and 77 of the series has already been referred to. The grade from each table passes over the table into a suitable inclined chute 115 and thence into a suitable receptacle, or it may. pass directly from the table to the receptacle.

From the description heretofore given itis believed that the operation of the machine will be fully understood, since the function of each part has been mentioned in connection with the description of its construction.

Having thus described my invention, what I claim is- 1. In an ore-concentrator, a mixer for rendering the comminuted material a homogeneous mass, said mixture being suitably located forreceivingthe materialtobe treated therein, and consisting of two contiguous circular compartments 35, having an opening 36 leading from one to the other, a vertical shaft 41, provided' with radial a1 ms, said shaft being suit- 'ably located and supported in the center of each compartment, and means for rotating said shafts, substantially as described.
